SPECIFICATION forming part of Letters Patent No. 673,679, dated May 7,1901.

Application filed January 28, 1901. Serial No. 45,046. (No model.)

T at whom it may concern:

Be it known that we, JAMES ELMER FOSTER and CHARLES FLETCHER RIoHEY,citizens of the United States, and residents of Franklin, in the countyof Venango and State of Pennsylvania, have invented a new and ImprovedPump-Rod Grip, of which the following is a full, clear, and exactdescription.

This invention relates to improvements in devices for gripping pump-rodsor other rods or pipes; and the object is to provide a device of thischaracter of simple construction and so arranged that it may be easilyattached to a rod or pipe and operated without danger of bending therodor pipe.

We will describe a pump-rod grip embodying our invention and then pointout the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a partofthis specification,

in which similar characters of reference indicate corresponding parts inall the figures. Figure 1 is a side view, partly in section,of a gripembodying our invention. Fig. 2 is a top view thereof. Fig. 3 is a planview, partly in section, of the grip-frame; and Fig. 4 is a side view ofone of the gripping-jaws.

The frame of the gripping device consists of two side pieces 1 and 2,from one of which a pin 3 extends through an opening in the other sidepiece and is held by means of a cross-pin 4 through said pin 3 andengaging with the outer surface of the side piece. Mounted to swing onthe pin 3 between the side pieces is a clamping-jaw 5, having acamshaped inner end to engage with a rod or pipe and having anoutwardly-extended stem 6, provided with an eye in which is engaged asection of a chain 7, the upper end of said chain-section beingconnected toa ring 8, with which a tackle is designed to be engaged.Coacting with the .jaw 5 is a removable jaw 9, having a cam-shaped innerend and provided with a stem 10, through the eye of which achain-section 11 extends to the ring 8. The removable jaw 9 is mountedto swing on lugs 12 and 13, extended inward from the side pieces 1 and2. These lugs are designed to engage in channels 14, formed in theopposite sides of the jaw 9 and opening downward and outward. The outeredges of these channels are provided with inwardly-extended flanges 15to engage against the inner sides of the heads 16, formed on the lugs.This, while permitting the jaw to swing freely onthe lugs, will preventthe side pieces of the frame from spreading outward relatively to thejaw.

This device is intended mainly to make connections between tackle-boxesand oilwell rod lines. When there is more than one oil-well on a lease,it is necessary to stretch iron rods from the well to the pumping power,which is located at some central point on the lease. The lines are givena backward-andforward motion, which works the rods up and down in thewell, and the rods sometimes break, allowing the rods or lines to sagdown between the carriers, which .are about thirty feet apart, and inorder to repair a rod it is necessary to pull the two ends together andhold them until repaired. This operation not only takes up all the slackof the iron, but must lift the rods in the well, which cannot be donewith a rod or chain hitch on the rod,

lugs 12 and 13, and then the framemembers passed along the oppositesides of the pipeand the jaw9 replaced.

Having thus described our invention, we

claim as new and desire to secure by Letters.

Patent 1. A rod or pipe gripping device, comprisinga frame having sidemembers, a grippingjaw pivoted between said side members, headed lugsextended inward from said side members, the jaw having channels in itsopposite sides to receive said lugs, and flanges extended from the sidesof the channels for engaging the heads of the lugs, substantially asspecified.

2. A gripping device, comprisinga frame having opposite side members, ajaw pivoted between said side members, lugs extended inward from saidside members near one end, the ends of said lugs being headed, a jawhaving outwardly-opening channels in its 0p posite sides for receivingsaid lugs, and flanges extended inward from said channels for engagingwith the heads of the lugs, substantially as specified.

3. A gripping device, comprising a frame having opposite side members, ajaw pivoted between said side members and having an outwardly-extendedstem, headed lugs extended inward from said side members, a jaw havingchannels in its opposite sides to receive said lugs, and flanges on thewalls of said channels for engaging with the heads of 1
